YB15WSKG01

Pushbutton Switches are versatile, hand-operated electrical switches used to control a circuit. The YB15WSKG01 pushbutton switch is used mainly in the telecommunications industry. This low voltage switch offers the advantages of low operating temperature, no moving parts, and a long life.

Application Field

The YB15WSKG01 pushbutton switch is generally used in circuits that control the connection of two electrical signals such as an audio signal or a data signal. An example of an application for this switch is the switch used to answer the telephone handset. When the switch is pressed the handset is connected to the call and the user can communicate. This type of switch is also used in modems, fax machines, and other telecommunications equipment.

Working Principle

When the YB15WSKG01 pushbutton switch is pressed, the internal contacts close providing a low impedance connection between the two points of the circuit. This closing action of the switch creates a circuit path that allows a flow of electrical current. There are two types of YB15WSKG01 switch, momentary action and latching action. In the momentary action the switch is held closed only when the button is pressed. When the button is released the switch opens, breaking the circuit and thus stopping the flow of current. In the latching action type, the switch will remain in the closed state even after the button is released. This type of operation is best for applications where momentary contact is required, such as in the telephone handset.
